The NU-CALGON NUCAL-4182-08 is a liquid gas leak detector solution designed to identify leaks in gas piping systems, fittings, and connections. Applied directly to joints and fittings, the solution produces visible bubbling at any point where gas is escaping, giving technicians a fast, reliable visual indication of the leak location. Supplied in a 1-gallon (128 oz.) container, this format is well suited for service vehicles, shop use, or situations where repeated application is needed across multiple connections in a single job.
Cal-Blue Plus is used by HVAC technicians, plumbers, and gas service professionals on natural gas and LP gas systems in residential and light commercial settings. Typical applications include testing newly made-up threaded or flared connections, verifying repairs after parts replacement, and performing routine leak checks on existing gas piping during service calls. The 1-gallon size provides ample volume for high-frequency use in the field or on the bench.
Designed as an OEM-style leak detection solution for use on natural gas and LP gas piping, fittings, valves, and connections in residential and light commercial gas systems.
Gas leak detection solution is applied by HVAC technicians and licensed gas fitters working on pressurized gas systems. Always ensure the system is at operating pressure before applying the solution so that any active leak produces a visible bubble response. Follow all applicable codes, including IFGC requirements, for leak testing procedures before placing a gas system back into service. Never use an open flame to verify a suspected gas leak.
